A bouquet of chromosomes.
During meiotic prophase, telomeres attach to the inner nuclear envelope and cluster to form the so-called meiotic bouquet. Although this has been observed in almost all organisms studied, its precise function remains elusive. The coincidence of telomere clustering and initiation of chromosome synapsis has led to the hypothesis that the bouquet facilitates homologous chromosome pairing and synap...
متن کاملMeiotic Proteins Bqt1 and Bqt2 Tether Telomeres to Form the Bouquet Arrangement of Chromosomes
In many organisms, meiotic chromosomes are bundled at their telomeres to form a "bouquet" arrangement. The bouquet formation plays an important role in homologous chromosome pairing and therefore progression of meiosis. As meiotic telomere clustering occurs in response to mating pheromone signaling in fission yeast, we looked for factors essential for bouquet formation among genes induced under...
متن کاملA bouquet of DNA structures: Emerging diversity
Structural polymorphism of DNA has constantly been evolving from the time of illustration of the double helical model of DNA by Watson and Crick. A variety of non-canonical DNA structures have constantly been documented across the globe. DNA attracted worldwide attention as a carrier of genetic information. In addition to the classical Watson-Crick duplex, DNA can actually adopt diverse structu...
متن کاملVon Willebrand factor folds into a bouquet.
The large glycoprotein von Willebrand factor (vWF) serves an important role in orchestrating the blood vessel’s response to injury. It is released from activated endothelial cells and forms long multimeric strings that bind exposed extracellular matrix and circulating platelets and thereby initiate the formation of a platelet plug sealing the wound. Central to this process is the rapid transiti...
متن کاملProjections of Bouquet Graph with Two Cycles
In this paper we investigate the projections of bouquet graph B with two cycles. A projection of B is said to be trivial if only trivial embeddings are obtained from the projection. It is shown that, to cover all nontrivial projections of B, at least three embeddings of B are needed. We also show that a nontrivial projection of B is covered by one of some two embeddings if the image of each cyc...
